tee 
miner, Epinotia nanana Tr. They were accompanied by C. W. Collins, in 
charge of the gipsy moth laboratory, during part of their trip. The 
observations made indicate that the infestations are much lighter than in 
1930, though feeding on both red and white spruce is noticeable, especial—' 
ly near the seacoast. Areas of spruce growth, each covering an acre or 
more, were examined and none were found to have an average defoliation 
of more than 35 per cent. The reason for the infestations being lighter 
than in 1930 is unknown, but it is possibly partly due to the unusually 
rainy spring of 1931. 
During June a number of shipments of parasites were received at the 
gipsy moth laboratory from the Budapest, Hungary, substation. These con— 
sisted of parasites of the European pine shoot moth, Rhyacionia buoliana 
Schiff., secured in Austria; parasites of the gipsy moth from Austria and 
Hungary; and parasites of the brown-tail and satin moths from Hungary. 
A small colony of adults belonging to the genus Tranosema was put out at 
North Conway, N. H., on June 16. This hymenopterous parasite of Phyllo-— 
toma nemorata Fall., a leaf-mining sawfly on birch, was received from 
Austria during the past winter. 
Two small shipments of adults of Mesoleius tenthredinis Morley were 
received at the gipsy moth laboratory in June from A. B. Baird, of the 
Dominion Parasite Laboratory, Belleville, Ontario, Canada. This hymen- 
opterous parasite of the larch sawfly, Lygaeonematus erichsonii Hartig, 
has been introduced from Europe and established in Canada. The adults 
received at the gipsy moth laboratory have been liberated in larch sawfly 
infestations in Massachusetts. A Shipment of puparia of the tachinid 
Laboratory from Melrose Highlands. Adults issuing from these puparia will 
be liberated at points in British Columbia where the satin moth is present.
